1.0 LIMITATIONS ON DISCLOSURE & USE OF THIS REPORT1.0 LIMITATIONS ON DISCLOSURE & USE OF THIS REPORT

This report contains information concerning potential vulnerabilities of eClipse Bank's network and

systems and methods of exploiting them. Cynergi recommends that special precautions be taken to

protect the confidentiality of both this document and the information contained herein. Cynergi has

retained and secured a copy of the report for customer reference. All other copies of the report

have been delivered to eClipse Bank. Security assessment is an uncertain process, based upon

past experiences, currently available information, and known threats. It should be understood that

all information systems, which by their nature are dependent on human beings, are vulnerable to

some degree.

Therefore, while Cynergi considers the major security vulnerabilities of the analyzed systems to

have been identified, there can be no assurance that any exercise of this nature will identify all

possible vulnerabilities or propose exhaustive and operationally viable recommendations to

mitigate those exposures. In addition, the analysis set forth herein is based on the technologies

and known threats as of the date of this report. As technologies and risks change over time, the

vulnerabilities associated with the operation of eClipse Bank's systems described in this report, as

well as the actions necessary to reduce the exposure to such vulnerabilities, will also change.

Cynergi makes no undertaking to supplement or update this report on the basis of changed

circumstances or facts of which Cynergi becomes aware after the date hereof, absent a specific

written agreement to perform supplemental or updated analysis.

This report may recommend that eClipse Bank use certain software or hardware products

manufactured or maintained by other vendors. Cynergi bases these recommendations upon its

prior experience with the capabilities of those products. Nonetheless, Cynergi does not and cannot

warrant that a particular product will work as advertised by the vendor, nor that it will operate in the

manner intended. This report was prepared by Cynergi for the exclusive use and benefit of eClipse

Bank and is deemed proprietary information. The Professional Service Level Agreement (SLA) in

effect between Cynergi and eClipse Bank governs the disclosure of this report to all other parties.

2.0 EXECUTIVE SUMMARY2.0 EXECUTIVE SUMMARY

This report presents the results of the vulnerability assessment and penetration

test of eClipse Bank's Internet banking web application and underlying Internet

and network infrastructure. The Internet banking online application is a web-

based access point for customers both corporate and individuals to conduct

ebusiness. This assessment was performed under the auspices of Cynergi's

CTO F.X One a certified and licensed penetration tester. The purpose of this

assessment is to identify application and network-level security issues that could

affect eClipse Bank's Internet banking application and network infrastructure.

The scope of this exercise includes the testing of the Internet banking application and all of its

functionality. To evaluate the security of the network and application, Cynergi attempted to perform

unauthorized transactions, obtain confidential information, and determine the overall security of the

application by performing a wide variety of vulnerability checks. The testing also included the servers,

operating systems and network devices associated with the bank.

This result is intended to be an overall assessment of the eClipse Bank's network, including that of

applications that fall within the scope of this project. Furthermore, the findings in this report reflect the

conditions found during the testing, and do not necessarily reflect current conditions.

3.0 INTRODUCTION 3.0 INTRODUCTION

At the request of eClipse Bank PLC, Cynergi Solutions Inc performed the

security assessment of the web application and underlying network

infrastructure. The purpose of this assessment is to identify network and

application-level security issues as well as vulnerabilities affecting the

servers and network devices providing access to the organization.

The objective of the analysis is to simulate an attack to assess eClipse Bank's immunity level, discover

weak links and provide recommendations and guidelines to vulnerable entities discovered. This report

is a report which contains sub-sections. Each Sub-section discusses in detail all relevant issues and

avenues that can be used by attackers to compromise and gain unauthorized access to sensitive

information. Every issue includes an overview, issues found and security guidelines, which, if followed

correctly, will ensure the confidentiality and integrity of the systems and applications.

Cynergi's assessment methodology includes structured review processes based on recognized

“best-in-class” practices as defined by such methodologies as the ISECOM's Open Source Security

Testing Methodology Manual (OSSTMM), the Open Web Application Security Project (OWASP) and ISO 27001 Information Security Standard

The testing was performed under the auspices and supervision of Cynergi's CTO F. X One from June

18 through July 23, 20XX. Phase One (Footprinting and Enumeration) of the test was executed within

eClipse Bank's office premises while phase two (Scanning, and Exploitation) was conducted via the

Internet from Cynergi’s security labs located within and outside the country.

This testing did not explicitly attempt Denial of Service (DoS) attacks against any of eClipse Bank's

systems. However, we performed the security assessment of the external network and web application

as an authorized and an unauthorized user. Login credentials to the Internet Banking system were

obtained as part of the testing process. This was a complete black box test simulating a typical

external hacker's view of the organization.

3.1 Project Objective

The objective of eClipse Bank's network and application assessment is to

determine the overall security of the application by analyzing all possible

transactions, user input variables, and application components that reside on

network systems. For the testing, Cynergi attempted to perform a full

application test as an authorized user (with log-on and password supplied to

the Internet banking application)

The objective of the security assessment and penetration test of the network infrastructure supporting

the application is to determine the overall security of the network segments and hosts within the scope

of the engagement.

3.2 Project Scope

The assessment performed was focused on eClipse Bank's external network and application

infrastructure and its related systems and the Internet banking application portal itself. The specific

systems and subnets tested are indicated in the next section titled “Target Systems.” This result is

intended to be an overall assessment of eClipse Bank's network, and those systems and subnets that

fall within the scope of this project. Furthermore, the findings in this report reflect the conditions found

during the testing, and do not necessarily reflect current conditions.

This testing did not attempt any active network-based Denial of Service (DoS) attacks. Password

cracking, physical, process and social engineering attacks were outside our remit. Internal

assessment was also not carried out.

6.0 FINDINGS6.0 FINDINGS

6.3.1 Issue Identification Each security issue identified by Cynergi is described with the finding, the impact of the issue, how

easy it would be for an attacker to exploit the issue and a recommendation. Each security issue is

rated based on a number of factors, each of these are described in the following sections.

6.3.1 Issue Finding

The issue finding describes what configuration setting we identified that potentially poses a security

threat. In addition to the finding details, any relevant background information is also described.

6.3.2. Issue Impact

The impact section describes what an attacker could gain from exploiting the security issue. The

impact of an issue is often defined by other configuration settings that could heighten the issue or

partially mitigate it. The impact is rated depending on the significance of the security threat.

RatingRating Description

CriticalCritical These issues can pose a very significant security threat. The issues that have a critical impact are typically those that would allow an attacker to gain full

administrative access to the device. For a firewall device, allowing all traffic to pass

through the device unfiltered would receive this rating as filtering traffic to protect

other devices is the primary purpose of a firewall.

HighHigh These issues pose a significant threat to security, but have some limitations on the extent to which they can be abused. User level access to a device and a DoS

vulnerability in a critical service would fall into this category. A firewall deivce that

allowed significant unfiltered access, such as allowing entire subnets through or not

filtering in all directions, would fall into this category. A router that allows significant

modification of its routing configuration would also fall into this category.

MediumMedium These issues have significant limitations on the direct impact they can cause. Typically these issues would include significant information leakage issues, denial of

service issues or those that provide significantly limited access. A SNMP service that

Security Assessment Report for eClipse Bank PLC Private & ConfidentialSecurity Assessment Report for eClipse Bank PLC Private & Confidential 2222

is secured with default or a dictionary based community string would typically fall into

this rating, as would a firewall that allows unfiltered access to a range of services on a

device.

LowLow These issues represent a low level security threat. A typical issue would involve information leakage that could be useful to an attacker, such as a list of users or

version details. A non-firewall device that was configured with weak network filtering

would fall into this category.

Table 6.1: Impact ratings

6.3.3. Issue Ease The ease section of each issue describes the knowledge, skill and physical access that would be

required of an attacker in order to exploit it. The ease will describe if open source or commercially

available tools are required for an attacker to exploit an issue. Additionally, the ease will note where an

extended period of time is required to exploit the issue, such as cracking weak encryption ciphers.

Each issue is rated upon how easily it can be exploited, the ratings are described in Table 6.2

Rating Rating Description

TrivialTrivial The issue requires little-to-no knowledge on behalf of an attacker and can be exploited using standard operating system tools. A firewall device which had a network filtering

configuration that enables traffic to pass through would fall into this category.

EasyEasy The issue requires some knowledge for an attacker to exploit, which could be performed using standard operating system tools or tools downloaded from the

Internet. An administrative service without or with a default password would fall into

this category, as would a simple software vulnerability exploit.

ModerateModerate The issue requires specific knowledge on behalf of an attacker. The issue could be exploited using a combination of operating system tools or publicly available tools

downloaded from the Internet.

ChallengeChallenge A security issue that falls into this category would require significant effort and knowledge on behalf of the attacker. The attacker may require specific physical

access to resources or to the network infrastructure in order to successfully exploit it.

Furthermore, a combination of attacks may be required.

N/AN/A The issue is not directly exploitable. An issue such as enabling legacy protocols or unnecessary services would fall into this rating category.

Table 6.2: Ease ratings

Security Assessment Report for eClipse Bank PLC Private & ConfidentialSecurity Assessment Report for eClipse Bank PLC Private & Confidential 2323

6.3.4. Issue Recommendation

Each issue includes a recommendation section which describes what steps Cynergi recommends

should be taken in order to mitigate the issue. The recommendation will sometimes include various

options, if several mitigating choices are available, and any relevant system commands.

Directly following the recommendation, the issue dependencies and other relevant issues are

referenced. The dependency issues are those that when mitigated will eliminate the described issue.

For example, if the Simple Network Management Protocol (SNMP) is disabled it no longer matters if a

view has not been configured. The relevant issues are ones that can affect the impact or the ease that

the issue can be exploited.

The recommendation includes a rating that indicates how easy an issue is to resolve, these are

described in Table 6.3.

Rating Rating Description

InvolvedInvolved The resolution of the issue will require significant resources to resolve and is likely to include disruption to network services, and possibly the modification of other network

device configurations. The issue could involve upgrading the Cisco PIX Security

Appliance OS and possibly modifications to the hardware.

PlannedPlanned The issue resolution involves planning, testing and could cause some disruption to services. This issue could involve changes to routing protocols and changes to

network filtering.

QuickQuick The issue is quick to resolve. Typically this would just involve changing a small number of settings and would have little-to-no effect on network services.

6.8 Internet Banking Assessment

Issue Description Severity Recommendation Cross-site scripting (reflected)

There are 5 instances of this issue:

https://secure.eclipsebank.cxm/g enScript.php [acctno parameter]

https://secure.eclipsebank.cxm/g enScript.php [bank parameter]

https://secure.eclipsebank.cxm/g enScript.php [edate parameter]

https://secure.eclipsebank.cxm/g enScript.php [sdate parameter]

https://secure.eclipsebank.cxm/g enScript.php [usr parameter]

Reflected cross-site scripting vulnerabilities arise when data is copied from a request and echoed into the application's immediate response in an unsafe way. An attacker can use the vulnerability to construct a request which, if issued by another application user, will cause JavaScript code supplied by the attacker to execute within the user's browser in the context of that user's session with the application.

The attacker-supplied code can perform a wide variety of actions, such as stealing the victim's session token or login credentials, performing arbitrary actions on the victim's behalf, and logging their keystrokes.

Users can be induced to issue the attacker's crafted request in various ways. For example, the attacker can send a victim a link containing a malicious URL in an email or instant message. They can submit the link to popular web sites that allow content authoring, for example in blog comments. And they can create an innocuous looking web site which causes anyone viewing it to make arbitrary cross-domain requests to the vulnerable application (using either the GET or the POST method).

The security impact of cross-site scripting vulnerabilities is dependent upon the nature of the vulnerable application, the kinds of data and functionality which it contains, and the other applications which belong to the same domain and organisation. If the application is used only to display non-sensitive public content, with no authentication or access control functionality, then a cross-site scripting flaw may be considered low risk. However, if the same

High In most situations where user-controllable data is copied into application responses, cross-site scripting attacks can be prevented using two layers of defenses:

Input should be validated as strictly as possible on arrival, given the kind of content which it is expected to contain. For example, personal names should consist of alphabetical and a small range of typographical characters, and be relatively short; a year of birth should consist of exactly four numerals; email addresses should match a well-defined regular expression. Input which fails the validation should be rejected, not sanitised.

User input should be HTML-encoded at any point where it is copied into application responses. All HTML metacharacters, including < > " ' and =, should be replaced with the corresponding HTML entities (< > etc).

In cases where the application's functionality allows users to author content using a restricted subset of HTML tags and attributes (for example, blog comments which allow limited formatting and linking), it is necessary to parse the supplied HTML to validate that it does not use any dangerous syntax; this is a non-trivial task.

application resides on a domain which can access cookies for other more security-critical applications, then the vulnerability could be used to attack those other applications, and so may be considered high risk. Similarly, if the organisation which owns the application is a likely target for phishing attacks, then the vulnerability could be leveraged to lend credibility to such attacks, by injecting Trojan functionality into the vulnerable application, and exploiting users' trust in the organisation in order to capture credentials for other applications which it owns. In many kinds of application, such as those providing online banking functionality, cross-site scripting should always be considered high risk.

SSL cookie without secure flag set

The following cookie was issued by the application and does not have the secure flag set:

PHPSESSID=dd06vet836kdto8 cvmvqmlo8d2; path=/

The cookie appears to contain a session token, which may increase the risk associated with this issue. You should review the contents of the cookie to determine its function.

If the secure flag is set on a cookie, then browsers will not submit the cookie in any requests that use an unencrypted HTTP connection, thereby preventing the cookie from being trivially intercepted by an attacker monitoring network traffic. If the secure flag is not set, then the cookie will be transmitted in clear-text if the user visits any HTTP URLs within the cookie's scope.

An attacker may be able to induce this event by feeding a user suitable links, either directly or via another web site. Even if the domain which issued the cookie does not host any content that is accessed over HTTP, an attacker may be able to use links of the form http://eclipsebank.cxm:443/ to perform the same attack

Medium The secure flag should be set on all cookies that are used for transmitting sensitive data when accessing content over HTTPS. If cookies are used to transmit session tokens, then areas of the application that are accessed over HTTPS should employ their own session handling mechanism, and the session tokens used should never be transmitted over unencrypted communications.

Cookie without HttpOnly flag set

The following cookie was issued by the application and does not have the HttpOnly flag set:

PHPSESSID=dd06vet836kdto8 cvmvqmlo8d2; path=/

If the HttpOnly attribute is set on a cookie, then the cookie's value cannot be read or set by client-side JavaScript.

This measure can prevent certain client-side attacks, such as cross-site scripting, from trivially capturing the cookie's value via an injected script.

Low There is usually no good reason not to set the HttpOnly flag on all cookies. Unless you specifically require legitimate client-side scripts within your application to read or set a cookie's value, you should set the HttpOnly flag by including this attribute within the relevant Set-cookie directive.

You should be aware that the restrictions imposed by the HttpOnly flag can potentially

The cookie appears to contain a session token, which may increase the risk associated with this issue. You should review the contents of the cookie to determine its function.

be circumvented in some circumstances, and that numerous other serious attacks can be delivered by client-side script injection, aside from simple cookie stealing.

Password field with autocomplete enabled

The page contains a form with the following action URL:

https://secure.eclipsebank.cx m/functions.php?action=login

The form contains the following password field with autocomplete enabled:

passwd2

Most browsers have a facility to remember user credentials that are entered into HTML forms. This function can be configured by the user and also by applications which employ user credentials. If the function is enabled, then credentials entered by the user are stored on their local computer and retrieved by the browser on future visits to the same application.

The stored credentials can be captured by an attacker who gains access to the computer, either locally or through some remote compromise. Further, methods have existed whereby a malicious web site can retrieve the stored credentials for other applications, by exploiting browser vulnerabilities or through application- level cross-domain attacks.

Low To prevent browsers from storing credentials entered into HTML forms, you should include the attribute autocomplete="off" within the FORM tag (to protect all form fields) or within the relevant INPUT tags (to protect specific individual fields).

Cross-domain script include

The response dynamically includes the following script from another domain:

https://siteseal.thawte.com/cgi /server/thawte_seal_generator. exe

When an application includes a script from an external domain, this script is executed by the browser within the security context of the invoking application. The script can therefore do anything that the application's own scripts can do, such as accessing application data and performing actions within the context of the current user.

If you include a script from an external domain, then you are trusting that domain with the data and functionality of your application, and you are trusting the domain's own security to prevent an attacker from modifying the script to perform malicious actions within your application.

Low Scripts should not be included from untrusted domains. If you have a requirement which a third-party script appears to fulfil, then you should ideally copy the contents of that script onto your own domain and include it from there. If that is not possible (e.g. for licensing reasons) then you should consider reimplementing the script's functionality within your own code.

TRACE method is enabled The TRACE method is designed for diagnostic purposes. If enabled, the web server will respond to requests which use the TRACE method by echoing in its response the exact request which was recieved.

Low The TRACE method should be disabled on the web server.

Although this behaviour is apparently harmless in itself, it can sometimes be leveraged to support attacks against other application users. If an attacker can find a way of causing a user to make a TRACE request, and can retrieve the response to that request, then the attacker will be able to capture any sensitive data which is included in the request by the user's browser, for example session cookies or credentials for platform- level authentication. This may exacerbate the impact of other vulnerabil

Email addresses disclosed

There are 2 instances of this issue:

• /functions.php • /welcome.php

The presence of email addresses within application responses does not necessarily constitute a security vulnerability. Email addresses may appear intentionally within contact information, and many applications (such as web mail) include arbitrary third-party email addresses within their core content.

However, email addresses of developers and other individuals (whether appearing on-screen or hidden within page source) may disclose information that is useful to an attacker; for example, they may represent usernames that can be used at the application's login, and they may be used in social engineering attacks against the organisation's personnel. Unnecessary or excessive disclosure of email addresses may also lead to an increase in the volume of spam email received.

Low You should review the email addresses being disclosed by the application, and consider removing any that are unnecessary,

Cacheable HTTPS response

There are 3 instances of this issue:

• /functions.php • /genScript.php • /ibanking_tranzalert.swf

Unless directed otherwise, browsers may store a local cached copy of content received from web servers. Some browsers, including Internet Explorer, cache content accessed via HTTPS. If sensitive information in application responses is stored in the local cache, then this may be retrieved by other users who have access to the same computer at a future time.

Low The application should return caching directives instructing browsers not to store local copies of any sensitive data. Often, this can be achieved by configuring the web server to prevent caching for relevant paths within the web root. Alternatively, most web development platforms allow you to control the server's caching directives from within individual scripts. Ideally, the web server should return the following HTTP headers in all responses containing sensitive content:

• Cache-control: no-store • Pragma: no-cache

file:///home/fx/proposals/skyebank/pt/scan1.html#4.3.2
file:///home/fx/proposals/skyebank/pt/scan1.html#4.3.1
Content type incorrectly stated

There are 2 instances of this issue:

• /ft_own.php • /ft_third.php

If a web response specifies an incorrect content type, then browsers may process the response in unexpected ways. If the specified content type is a renderable text-based format, then the browser will usually attempt to parse and render the response in that format. If the specified type is an image format, then the browser will usually detect the anomaly and will analyse the actual content and attempt to determine its MIME type. Either case can lead to unexpected results, and if the content contains any user-controllable data may lead to cross-site scripting or other client-side vulnerabilities.

In most cases, the presence of an incorrect content type statement does not constitute a security flaw, particularly if the response contains static content. You should review the contents of the response and the context in which it appears to determine whether any vulnerability exists.

Low For every response containing a message body, the application should include a single Content-type header which correctly and unambiguously states the MIME type of the content in the response body.

7.0 CONCLUSION7.0 CONCLUSION

This analysis is based on the technologies and known threats as of the date

of this report. Cynergi recommends that all modifications suggested in this

document be performed in order to ensure the overall security of the web

application and Internet segment. Specifically, the following action should be

taken:

• Password protect the FTP Administrator account on the Internet application server

• We also recommend that the issue of the reflected cross site scripting on the Internet banking web

application be looked into

• The eclipsebank.cxm web hosting provider should also be contacted with a view to effecting the

recommended security controls on the webserver.

All in all we found that the current security posture of the systems and applications within the scope in

decent shape from an external point of view although as with most networks there is room for improvement.

Nevertheless, we suggest that eClipse Bank implement the recommendations in this document with

respect to the affected servers and applications. We also propose that eClipse Bank perform a follow on

retest to verify that the recommended changes were made and made correctly. Technical raw data

aggregated and collected from the security assessment has also been made available in the appendix for

reference.

Please note that as technologies and risks change over time, the vulnerabilities associated with the

operation of the systems described in this report, as well as the actions necessary to reduce the exposure

to such vulnerabilities, will also change. Cynergi makes no undertaking to supplement or update this report

on the basis of changed circumstances or facts of which we become aware after the date hereof, absent a

specific written agreement to perform supplemental or updated analysis.

Cynergi has appreciated this opportunity to perform the assessment and testing service for eClipse Bank

PLC. We hope that the information contained in this document is of benefit to your organization. As eClipse

Bank's security related needs arise again in the future, it would be our pleasure to serve you again.
